Decided to go for this upgrade when the Jeep went into the shop for a transmission rebuild. The improvements in drive-ability, emissions, fuel economy, and torque are nothing short of amazing. I use my KJ to tow a race car all summer and it's an occasional commuter during the rest of the year. Fuel economy has improved 2 MPG under tow to a miraculous 22mpg pulling 4,000 lbs down the interstate. No more black smoke, even when hammering the throttle. It's no joke that the stock torque converter is not up the power this tune puts out. I told the transmission shop to upgrade 5th gear and the torque converter, they did 5th gear but mistakenly put a stock spec torque converter in. It shuddered up every hill when in lockup on the stock spec converter and the shop had to replace it with a beefier unit. Highly recommend this for the simple efficiency gains alone, but the added capability under tow knocks it out of the park.

I purchased the Hot Tune and plan to manage the power by feel... heavy and on steeper highway hills, I turn off overdrive to protect the torque converter. Otherwise, it is excellent to drive under normal conditions.
The new power and performance are impressive and as advertised 100%. I drive from Savannah into the NC Mountains to 3000' to 5500' and the extra power and fuel economy is awesome. The exhaust smoke is going away too now that the residuals are burning away out of the pipes and muffler; I probably have a couple thousand miles on the kit now with half interstate driving.
I recommend this to anyone looking for a nice bump in performance that you can count on. Easy to load into the vehicle and very good customer support too.

I purchased a GDE Hot tune for my 2006 Jeep Liberty, now my torque converter won't hold the 330+ ft-lbs of torque. What is the procedure for doing the transmission tune? Do I have to get under the Jeep?
Thanks,
Jerome

Bought the Flash Tool and the Eco Tune for my 2006 LIberty CRD. I recently had problems with it so I took it apart and did Elephant Hose Mod, Cleaned off the MAP sensor as it was caked with gunk from EGR and CCV systems. I have to say while I know cleaning the gunk off the map helped that after just 225 miles of driving it's great.
The Jeep's throttle is much more responsive. I've took it for a test drive, cold start, highway miles, 29 F, and got a return of 29.9 mpg. I am very pleased thus far with my purchase of the tune and flash tool.
I will definitely be a return customer as I intend to get Hot Tune when I switch out TC. Keith was very nice, he e-mailed me over a year ago with questions I had on the tune and mailed my tune to me on CHRISTMAS DAY! I was not expecting it till after the holidays.
THANKS GUYS AT GDE! Your hard work is much appreciated!

Great tune, you could easily tell the Jeep had more power. It's great to see my Jeep finally got the power it deserves.
My previous best tank prior the Hot tune was 28.2 averaging below 60 for a point of reference.
My first tank returned 28.4 mpg when traveling from central Florida to Atlanta with bad traffic. My previous best tank for that route was only returned 27 (with no traffic).
My second tank averaged 29.2 mpg from Atlanta to central Virginia. Since then, I am averaging about 28-32 mpg for my daily work route and am loving the tune. I would highly recommend it.
